lie it known that l. BENJAMIN D. CHAM- uizuLix. a citizen of the linitedStates of .unerica. and a resident of Corning, New York. ha veinvented'certain new and useful Improvements in Apparatus for theProduct-ion of lass Articles. of which the fol' lowing is aspecification.

This invention relates to a machine by which a gather of glass on ablow-pipe marvel-ed. and then blown in a n iold. The

particular machine shown herein is one adapted to receive and rotate aremovable blow- -pipe with the gather ofglass thereon, and when inmotion l j an attendant, to

ause. the gather n tr into contact who a marverer, on which it is;inairrered. a'l ter which the blowpipe is positioned vertically over amold to permit elongation. its rotation at this time being arrested toprevent a twisting of the gather which would result if the center ofmassof gather be out of the axis of rotation. .ii'tcr a proper period forelongation the mold is closed andtlie bulb blown. the mold opened andcooled. and the hull) moved away i'ron'i-the mold. To accomplish theseresults the machine includes a frame. pivoted on a horizontal trunnionand vharinga chuck and support adapted to receive and hold a removableblowpipe: a marverer located adjacentto the plane in which the blo\vpipecarried in such lrame. oscillates and a mold located in the axial lineof such blowpipe when vertical. \Yith' these parts is associated powerdriven mechauisnrfor r0- tating' the liloiv-pipez for oscillating; theframe to lift the gather on the blo .v-pipe. where-by itv will be rolledalong the face of the marverer: for retracting the marvcrer away fromthe blow-pipe when the marvering is finished. and for lowering thegather until the; blow-pipe is vertical and over the. mold. combinedwith automatic n'ieans' for arresting the rotationoi" the blow-pipe whenvertical.

It further comprises power driven means for manipulating the mold. andagain rotating .the blow-pip and means for admitt'inn' air to theblow-pip! at proper times.

in which it is desirable to serve as many machines as possible from asingle furnace,

e pipe to be brought v the lower and gearing them to the same drivingpower,

whereby further mined.

Certain features of the machine, such as means for arresting therotation of the-blowiron during elongationmeans dering the control ofthe blow-pipe to the mold when the latter closes, the means foreffecting the blow out and a new and improved clutch for the blow-pipe.,possesscs utility which is not-restricted to a machine of the characterdescribed, but are generally applicable to glass blowing machines.

My invention further consists in the construction. arrangement andcombination of the several parts embodied in such machine as will behereinafter more fully descril'fd and claimed.

Fig. 24 is a fragmentallongitudinal section of the blow-out mechanism shown in Figs. 22 and 23.Fig. 25 is a detail illustration of the wiper plate and its mounting. rThe main frame of the machine may be broadly described as a flatvertical web. 1, roperly strengthened by surrounding auges which arebroadened out at the botform a base. The lower rear part of the web ofthe frame is-removed to receive 2, which by the pinion 2, drives thegear 3 fast on the shaft 3 which is longitudinally mounted in the frame.The front end of the shaft carries a pinion 3 and the rear end oftheshaft drives, by means of the belt 3, a longitudinal shaft at mounted inthe top of the frame and having on its forward end a beveled pinion 4.The

. shaft 4 alsoimparts motion to the piston 5 of an air pump 5 mounted inthe upper rear part of the frame. as compressed is delivered to areservoir 6, formed by an offset portion 1 of the upper part of theframe web, and by a cover plate 6. In front of the base of the frame andsuitably attached thereto is the mold coolin tank 7.

n that form of the invention which is preferred the parts abovedescribed are com mon to two blowing and moldingdevices whiehare indeendent in their action, each forming an in ependent unitlocated'uponopposite sides similar view of on lines m -a: of Fig.

Fig. 11 isthe shaft 8.

From the pump the air poses of imparting motion to these separatedevices there are mounted longitudinally and side by side in the frameabove the shaft 3, two shafts 8, each ofwhich has In some the pinion 3".figures of the draw ofthe frame, and for the pur- 'sleeved thereon apinion 8 meshing with ings the two units are shown, and in others forsimplicity only one, are similar in all respects only one but inasmuchas they of them will be'here described, it being understood that itshould be desired to use the other it' would be constructed in the samemanner and be located upon the opposite side of the .1 I

frame symmetrically with that which will be referred to.

The pinion 8 sleeved in the shaft 8 is adapted to be locked thereto by aclutch 9 shown in detail in Figs. 11 to 15. As there shown this clutchcomprises four segments 9. contained within the internal igroove 8 ofthe hub of the pinion and adapted to'be pressed outwardly V rear beveledends of wedges 9 projecting in recesses between the adjacent ends of thesegments 9, the wedgesbeing guided in longitudinal slots cut in theperiphery of a sleeve 9 keyed to the shaft 8. The forward. ends of thewedges are contained in and fastened to a collar 9 slidably mounted onthe shaft and' provided with an annular move 9 in which engages a yoke10, by which the collar may be forced rearwardly tocause the wedges toexpand the clamping segments 9 and thus lock the pinion 8 to \Vhen soshoved rearwardly the clutch will remain locked until the .collar isforcibly drawn forward. The shaft 8 when locked to the pinion S asbefore described, drives, th-rough a worm 11 on its forward end, a wormwheel 11 mounted on a stub shaft 11 on the side of the main frame andnear the front'thereof, theworm wheel being fast to a disk 12, fromwhich the various movements, except that of the 1 rotation of theblow-pipe, attendant upon the operation of the machine, are derived.

The top of bifurcated and formed into two arms 13, each of whichlaterally projects beyond the corresponding side of the main frame andhas formed therein a transverse bearing 13, to receive the hollowtrunnion 1 1, of the blow-pipe frame 14:, which, as shown, con sists ofa piece of angle iron of suitable length, on one end of which(hereiircalled the upper or rear to bear thereon by the j the front ofthe main frame is i end) is mounted a blow- I pipe chuck 15, while onthe opposite (or lower or front end) of the blow-pipe frame is theblow-pipe support 17, adapted to receive a blow-pipe. of these partswhich is preferred will be hereinafter described. The trunnion 14 of theblow-pipe frame extends through the bearing 13 and has fast on its innerend a The detail construction i the side of the frame, the horizontalarm of the bell-crank projecting rearwardly 'from its pivotal point andcarrying a roller 18, contained in aieam track 19 on the outer side ofthedisk 12, the two arms of the bell-crank being in 'diiferentwerticalplanes. This track comprises a portion 19 by whichthe lower end of theblow-pipe frame, through the segment, will be slowly lifted on therotation of the disk from normal position, a portion 19 by which it willbe lowered, a concentric portion 19 which permits the rotation of thedisk when the frame is lowered without affecting the *po-' sition of theblow-pipe frame, andapor- 'tion 19 by which the blowpipe frame will bequickly lifted back to its normal hori: zontal position.

In a bearing 20 projecting from the side of the main frame near itsbottom at the front end thereof is journaled a tubular shaft :20, havingfast thereon a pinion segment 20*, meshing with a rack segment 21,carried on the depending arm of a bellcrank 21 journaled at 21 to theside of the main frame, the upper arm of the bellcrank engaging in a camtrack 21 on the inner face of the disk 12. The forward end of thetubular shaft 20 terminates in a cross head 20, on the forward end ofwhich is pivoted by a pivot pin 20 parallel with the axis of the moldcavity, the two halves 22, of the separable mold. The cam track 21 has aportion 21 so shaped that it will impart such motion to the hell-crank21 as to oscillate the tubular shaft through a limited arc, sutlicientto drop the mold halves into the water of the cooling tank 7 and thenraise them. this occurring while the blow-pipe frame is being swungrapidly upward to normal horizontal position.

lVithin the tubular shaft 20 is mounted for axial and rotary movement ashaft 24, which'extends outwardly beyond the cross head 20, and hasslidably mounted th a-eon collars 22 and 33 The collar 22 last on theshaft and has two diametric .ly opposite trunnions. the lower of whichis journaled in a rearward extension of the mold half while the otherreceives the forwardly extending arm of a bell-crank 2P journaled at 2 tin the rear end of the cross head 20, the opposite arm of the bell-crankbeing (mnnected by the link 2% with the opposite half 23, theconstruction being such that as the collar 22 is pressed inwardly themold halves are closed, and that as it is moved outwardly they areopened. To accomplhh the inward movement of thecollar 22 is the functionof the collar 23 which, is loose on the shaft 24, a spring 25 beinginterposed between it and the collar 22 to cushion the closing movementand to providea certain resiliency. The collar 23 has v trunnionsthereon which are mounted in the bifurcated end of the forwardlyextending arms of a bell-crank 26, pivoted at 26 to a bracket 26projecting from the side of the main frame 1, the laterally extendingarm of the bell-crank beingiconnectedby a universal. joint 27 withthedepending arm of a second bell-crank 28, pivoted at 28 on the side ofthe main frame, the upper arm of the last named bell-crank havingthereon a roller 28 held on the peripheryof the disk 12 by a spring 28,there being sufficient play in the parts forming the universal joint toallow for the versed-sine of-the are described by the lever 26 in movingfrom the of the mold to that corresponding to the closed positionthereof. A peripheral enlargement or cam 28 is mounted upon the disk insuch position that, when the concentric run 19 of the disk is holdingthe blowpipe frame vertically, it will, by striking the roller, actuatethe bell-cranks 28 and 26 to shove thecollar 23 inwardly on the shaft24,.and thus, through the interposition of. the spring25, close the moldhalves. lVhen ball bearings, a shell 15". in which is pivoted aplurality of jaws 15", the free ends of which project forwardly andwhich may be forced inwardly toward the axial line of the chuck by asliding collar 15? to engage an annular groove 30 in the upper end ofthe blow-pipe 30 when the latter has been inserted therein by anattendant. The rear inner edge of the collar is beveled at 15' and bycontacting on its rear movement with the rounded outwardly projectingnoses 15 on the front ends of the jaws closes the latter upon the pipewith sufficient force to clamp it securely, the jaws being held in thisclamping position by the inner cylindrical wall l5 of the collar, whichis normal to the arc in which the jaws swing and which by the finalrearward movement of the collar is brought upon the outside of the noses15 The gather end of the blow-pipe after its upper end is placed in thechuck is inserted in a support 17, comprising four antifriction rollers17 mounted in pairs on the angularly bent ends 17*, of levers 17, piv-.position corresponding to the open position oted at 17 intermediate oftheir ends, upon the bottom web of the blow-pipe frame at the forwardend thereof, the rear ends of such levers being connected with eachother by the toggle-levers 17, which are also pivoted at their adjacentends to the forward end of a rod 17, mounted in a guide17 on theblow-pipe frame, the rod being pro- I jected forwardly by a coiledspring 17 in- 31, the rear end of which is connected to the i. inner endof a hand lever 31 pivoted interv mediate of its length at 31, to thebottom terposed between the guide and a block 17 fast'on the rod,whereby the forward ends of the levers will be pressed together, closingthe rollers on the blow-pipe. For the purpose of separating the-pairs ofrollers to insert the pipe therein the lower end of the block 1'2projects through a slot in the bottom web of the blow-pipe frame, andhas connected thereto the forward end of a link ment of the sleeve torelease the upper end of'the pipe,.thus permitting the ready re moval ofthe latter. 1

' vUnder certain circumstances, it may be desirable during the moldingand blowing that the lower end of the blow-pipe be free to move slightlyto allow for imperfect al'inement of the blow-pipe frame with the moldsalthough in the machine which I have' constructed this is not so. Inorder to prevent it when wanted the following construction may be used:A lever 33 is pivoted on the bottom surface of the .web of the blowing.frame, near the forward end thereof, which lever projects inwardly pastthe inner edge of the blow-pipe frame and is pivoted to the link 31,where it crosses the latter,-

and a cam 33 is fixed upon. the upper surface of the hub of thebell-crank 18* on which ca in when the blow-pipe frame moves intovertical'position for blowing, the said inner end of the lever 33 isadapted to ride,

- being lifted thereby, and retracting the link 31, whereby the guiderollers 'will be separated. This separation of. the guide rollers atthis time due to the cause stated, does not however result in a loosingof the blow-pipe clutch, as the connection between the link 3.1 and thehand lever Bl us mZ-de by a slot 31,

in the former. It is furthermore desirable 1,124.,eee

that,.when the blow-pipe clutch and support have been actuated torelease a blow-pipe upon which an article'has' been finished,

means be provided to hold them in this posi-' V tion until another pipehas been inserted 70 and this is accomplished by a groove 34 in the rearend of the rod 17, in which groove one end of a spring pressed trigger34;is adapted to engage when the rod has been retracted, the oppositeend of the trigger having an inclined face 34 thereon, which facecoacts. with. a 'corresponding face 34 on the link 32, whereby, when thelink is.

shifted to shove the chuck collar rearwardly, the opposite end of thetriggerwill 30 v be drawn out of the seat on the rod and the latterreleased to be projected forwardly by the spring 17'.

The chuck shell has a packing 35 in its rear end surrounding an axialaperture 35, the end of the blow-pipe taking against the packing, andthe chuck block 15 has-an air passage 35", registering. with theaperture35 and connected with an air pipe 35 which enters the hollow trunnion141 of the blow-pipe frame, through a head 35 on the outer end thereof.The inner end of the trunnion has a corresponding head 35 which has acentral packing box' 35. Into this packing box projects the end of thepipe 35 the opposite end of which is connected to an air valve casing 36mounted on the forward end of the air chamber 6 between the. arms 13 ofthe main frame and connected with the interior of-the chamber. Asuitable valveishontained in the casing, the stem 36% ofwhich rests onthe horizontal 7 arm of a bell-crank 36 horizontally pivoted at 36 on abracket 36 projectingfrom the The other arm of side of the main frame.side lever has journaled therein aroller 36, running upon a crown cam36, on'the inner face of the disk 12, the roller being tangential to thecircle of the cam. The cam is' so shaped that the valve containeil inthe valve casing will be moved to admit air from the air chamber to theblow-pipe for molding and if desired for a blowingout of. thegatherimmcdiately after marvering.

. It, is preferable however to .obtain'the air ilo pressurefor thisblow-out from an auxg iliary air. supply, in the form of a combined pumpand air valve located in the connection between the air'reservoir. 6 andthe blow-pipe, chuck, which forces a limited 12cquantity of air into thegather for theblow out, and holds for a limited time the pressure thuscreated therein by sealing the end' of the blow-pipe and which thenreleases such' pressure and restores the connection between theblow-pipe and its air supply to permit the air for molding to beintroduced into the blow-pipe from the air reservoir when the air valvestem 3G is actuated. A

. form of this is shown inFig. 20, comprising 1 39 fast to the rear ende and incloses a piston valves 32", and having forward end adapted therear end of 1 closed end ot the iciileted to an arm inner side of i d orthe shaft t 38". mountpiston head is prothe cylind by a spring M dlocated on r such position that as the wings downwardly into l, tactingwith e t :ter through a es therefrom,

The idler is driven by the beveled gearingdO on the doubl ace gear ring 410, sleeved on t the b ow-pipe frame outgtlleieot. the crowned s ring being driven by inter end of a trans if,ionrnnled innrm 13 of the mine in oi the bearing 13. f i't ii hasthereon a ine inner end of beveled gem- '-l-? driven h re beveled 9in- 2bezirin or such an upward movement of the gather by which it is rolledalong the marverer (to be hereinafter described) a. movement of themarverer away from the vertical plane of movement of the gather, theadmission of,

a puff of air to swell the gather, a downward movement of the marveredgather until the blow-pipe is vertical and the gather is in position tobe centered within the mold cavity, a closing of the mold and theadmission of the molding air, an opening and dipping of the mold partsfor coolmg,and the 'igetnrn of the blow-pipe frame with the blON-PlPQtherein to horizontal position. It is desirable that a period, thelength of which depends upon the condition of the glass, etc, elapsebetween the time at which the blow-pipe becomes vertical and the closingof the mold to permit elongation, and it is further desirable duringthis period that the rotation of the blow-pipe be arrested. For thispurpose the following mechanism is used, which in conjunction with themain clutch, further provides means for initiating the operation of themachine. The yoke 10 of the main clutch is a rigid pendant on thecentral part of a substantially horizontal lever'lQ, pivotedintermediate of its length at $2 on the side of the main frame, theforward end of which lever lies under a depending finger 41 5 on thecentral portion of the controlling lever 43, which is mounted by havingits opposite ends guided in slots 43 in the end flanges l of the mainframe, both of said ends being normally held at the top of the slot bysprings 43, and thus the depression of either end of the controllinglever depresses the central portion thereof, and the finger 43 thereonby depressing the forward end of the horizontal lever 42 moves the yokerearwardly to engage the main clutch, which will be held in drivingconnection by the friction of its parts. To permit the desiredmanipulation of the controlling lever'its forward end is formed into ahendle and its rear end has pivoted thereto the upper end of a link 44,the lower end of which is connected to the rear end of a pedal Msupported at its front end from the base of the frame, and carrying atan intermediate point the pedal 44, by which the clutch may be closed tostart the movement of the machine after. the blow-pipe has been plhcedin the blow-pipe frame. A

hammer is pivoted above the yoke lever,

For the purpose ofautomatically causing the hammer to'ifall when the blow-pipe has by therotation of the disk 12, driven through the clutch, been positionedvertically, the dog is provided With a tail, having a pin 46 located inthe path of a peripheral cam 47 on the disk, whereby therotationof thelatter at the time stated,

by tripping the dog, permits the descent of the hammer to open theclutch,to arrest the rotation of the disk 'with the horizontal armo'fthe blow pipe frame actuating bellerank 18 in theconcentric runthereof. After the expiration of a proper period to permit elongationoffthe gather, the attendant depresses the handle of the controllinglg;le-

Duringthe initial part of this final rotation of the dis'kthe bl vvQ-pipe'remains stationary, due to the concentric portion 19 of the run in thedisk, this corresponding to the blowing'period' When the bI W-PIP Withthe blown article thereon has been re;

moved and another substituted therefor, the controlling lever is thrownby the pedali and the rotation oi the disk 12 resulting therefrom causesthe second peripheral pro-.

jection to again cock the hammer and set it for disengaging the clutchat the elongation of'the gather on such last named pipe. To' arrest therotation of the blow-pipe during the elongation, the followingconstruction is used: The beveled gear 11 issleeved on the shaft 41 andimmediately beside it is a collar 48, keyed to the shaft and having anannular groove'48 and having 'guided there in for axial movement a pin49, which is normally projectedby a spring 49 iiito recess in the sideof the gearfwherebythe lattcrwill be normallylocked to the shaft;

Thislever is pivoted intermediate of its length to a bracket 51 upon the topof the bearing 13 and its rear vend is normally,

held out of the annular groove 48* of the I collarAS by the engagementof the front end of the lever with catch 52, mounted upon the outerfaceof aspring standard 52, arising on the. inner side of the lever fromthe main frame, the catch being over the front end of the lever when therearend thereof is raised out of the groove, and normally maintaining:it" 'gin this p'ositio upwardjend of the "s'p'ring standard his anoutwardly extending stud 52 thereon, Ininating in a' beveled face. Ontheface of the blow-pipe frame, in the rear of thetrunni'on thereoflismounted a pivoted striker 53, having its front inner end bev eled as at53*. 'When the blow-pipe frame swings to position theblow-pipe'vertically for elongation, the beveled face o'n"the strikercontacts with the bereled end'o'f the stud 5'2", and presses the springstandard in Wardly, releasing the le e'r 50 and permitting the spring 52to thron the rear end of the leverfintothe groo' 'e of the collar 48,The rotation of the collar With the gear 41 will bring the pin 49therein against the beveled face'50 on the lever and the pin will beshifted axially thereby and will be drawn from the gear 41",disconnecting the blow-pipe from the motor and permitting it to come torest. To reiingage the clutch after the elongation and to'cause the pipeto resume its rotation duringthe molding, the

forward end of the lever 50 is connected with the corresponding end ofthe controlling lever 43, by a link 54, Whereby'as the former is moved'by itshandle to reengage th'e 'iriain clutch after the elongation, the

lever-Will also be shifted toraise the rear end the reof out of thegroove in the collar i8, permitting the pin 49 to be again shot toengage the gear 41". This movementot the clutch handle may be effectedby an at tendant who stands facing the machine and who has thrighthandunit opposite his left hand or it maybe accomplished automatically bythe elongationof the" gather by mechanism. Mechanism suitable for thislatter. purpose is shown for instance in British patent to Marks 5795of191 1f To per mit the return of 'the controlling lever to normalposition after the lever been positioned to cause the reengagement ofthe blOiV-PlPG rotatin clutch (whenthe-lever will be held by the catch52) the link 54 is connected to the lever 50 by a slot conned-- tion"54. ,ItWill be'noted that -when the blow-pipe frame swings back tohorizontal positionfafter the molding, the 53 magmas will turn on itspivot to pass the stud 52 on the. spring' standard 52 without causingmovement thereof. 7

desirable however that the marverer be ke tout of contactwith the gatherupon the e; scent of the blow-pipe and this is accomplished by thepivotal mounting of the former just described, as the rearwardlyextending arm 56* thereof is connected by the rod 561 with the upper arm57 of the vertical shaft 57 journaled in the marverer frame in thebearin'g 58 the lower end of the shaft having keyed thereon the head 57,

carrying on its rear end a roller 57 adapted to be pressed outwardly bya cam 57 adthe latter has swung forwardly in the direction of the arrowin Fig. 8 to an extent is reversed to lower the gather, until at the endof such movement, a striker arm; 58" upon the forward end of the racksegment lifts the latch and permits the compression spring 58 upon therod 56 to again throw the marverer back to normal position. It will benoted that this spring serves resiliently to hold the marverer againstthe gather during the marvering. The marverer plate may be cooled by ajet of air directed against it, by a suitable nozzle 58 as shown inFigs. 1 and 7, or its temperature may be controlled by making it hollowand circulating therein a suitable fluid in,

Such aplate may be adjustably mounted on its standard 59" on the front of thecooling tank, being offset from the standard, as shown, to permitthebody of the blown articles to .passthe lat ter when the blow-pipe framereturns to normal position, the plate itself being in the proper planeand at the proper elevation to contact with that part of the marveredgather which is to formv the neck of the article. eThe effect of suchcontact is not only to reduce the diameter of, the'gather at this vexface of the wiper) to permit the mold of the lower part of the gather.
